Part of the Whole

Below is the error I get.

"Oops, try again. get_class_average([alice]) resulted in an error: 'tuple' object has no attribute 'append'"

Problem occurs with the get_class_average function.


lloyd = {
    "name": "Lloyd",
    "homework": [90.0, 97.0, 75.0, 92.0],

# Add your function below!

@micah.edelblut,
Remove the comma-,
from

results = []

in your get_class_average function.
